SPECIFICATION forming part of Letters Patent No. 770,545, dated September 20, 1904.

Application filed May 18, 1903. Serial No. 167,517. (No model.)

To all whom, it may concern.-

Be it known that 1, YUsUKE TAMAMURA, a

subject of the Emperor of Japan, and a resident of Ash'io, in the Province of Shimozuke,

Japan, have invented a new and useful Improvement in Hoisting and Conveying Apparatus, of which the following is a specification. In the accompanying drawings, Figure l is a side view of an apparatus containing my invention. carriage. Fig. 3 is an end view of the loadcarriage. Fig. 4 is a vertical transverse section of the load-carriage. Fig. 5 is a vertical longitudinal section of the load-carriage. Fig. 6 is'a horizontal section of the load-carriage on the line we of Fig. 5. Fig. 7 is a longitudinal section on the line 1 y of Fig. 5. Fig.

Fig. 9 is the load-carriage of the modification.

A B are the head and tail supports of a trackway O, upon which the load-carriage D travels. I

E is the load, and F the fall-block.

G is a rope-actuator, which in the form shown consists of the two drums g g,.oper atively connected to move in'unison by being fixed on the same driven shaft 9?.

H is a counter-actuator, which in the form shown consists of the counterweights h h and the rest if.

I is the operating-rope, which in the form shown consists of the run 2' from the drum 9 to the head-support sheave 1, the runs to and from the counterweight-sheave 2,the run i to the tail-support sheave 3, i the run 6 to the tail-sheave 4, the rune" to the tail-support sheave 5, the run a to the load -carriage sheave 6, the run i to the fall-block sheave 7, the run a to the load-carriage sheave 8, the run i to the head-support sheave 9, the runs a to and from the counterweight-sheave 10, and the run t to the drum g. The rope I is coiled inversely on the drums g 9, so that by movement of the actuator G in either direction one drum pays out the rope as the other hauls it in. Detaining mechanism, the preferable form of which is hereinafter described, is provided whereby the travel of the rope-runs i and i over their supportingsheaves 6 and 8 respectively, is alternately Fig. 2 is a side view of the load block.

' prevented and permitted. When the travel of both the runs t and i is prevented, the actuator G will move the load-carriage D back and forth along the trackway C, the length of the fall-loop t' i remaining constant and the counterweights it and it being stationary upon the rest 73. When the travel of the run '5 is prevented, but of t' permitted, as shown in Fig. 1, the movement of the actuator G will shorten ,or lengthen the fall-loop and raise or lower the fall-block, the load-carriage D remaining stationary and the counterweight it also remaining stationary on the rest [L2, but the counterweight it being lowered or raised inversely to the fall- When the travel of the run 2' is prevented, but of t permitted, the movement of the actuator G will shorten or lengthen the fall-loop and raise or lower the fall-block, the load-carriage remaining stationary and the counterweight it also remaining stationary on the rest if, but the counterweight It being lowered or raised inversely to the fallblock. which the travel ofthe rope I over the sheaves 6 and 8, respectively, shall be detained the operator of the actuator Gr may control the raising or lowering of the fall-block or the conveying of the same by the movement of w the carriage along the trackway.

For adjusting the position or taking up the slack of the rope I a means of adjustment 47 may be connected with the block of the tail- Hence by locating the two points at sheave, and the two drums g and 9 may be inversely adjustable relatively to each other. The carriage-frame, by which the sheaves 6 and 8 are supported, consists of the side plates 11 l2,rigidly connected together and rigidly suspended by the hanger 13 from atruckframe 14:, pivotally supported by the trucks 15 and 16 on the wheels 17 18 19 20.

. j are two projections or enlargements formed in or upon the rope, each of which preferably consists of two members 21 and 22, attached, respectively, to the adjacent ends of rope and connected together by a universal joint 23.

The detaining mechanism preferably consists of two-detaining members is and 7c,which are alike in construction, but which are mounted, respectively, concentric with the sheaves 6 and 8, facing each other. They are so mounted as to be capable of oscillation between the positions occupied by it in Figs. 2 and 5, respectively. Each of these detaining members consists of the two side plates 24 and 25 on opposite sides of the sheave rigidly secured together beyond the periphery of the sheave and each carrying the forked projections 26 and 27 in such position that the opening between the forks of each projection oscillates in the plane of the sheave, and consequently of the rope I. The distance between the two forks of each of the projections 26 and 27 is suflicient to freely receive the rope, but not to permit of the passage of the rope projection or y". The rope is constantly held in the fork of the projection 27 by the cross-piece 28 between the extremities thereof; but, there being no con nection between the extremities of the forked projection 26 and it being shorter than the forked projection 27, it oscillates freely into and out of engagement with the rope. Each detaining member 70 and It" carries a projection 29, which cooperates with latching and unlatching mechanism, hereinafter described, so that when latched the detaining member is held in the position of is, Fig. 2, where the rope projection j is detained between the forked projections 26 and 27 but when unlatched the detaining member drops into the position of k, Fig. 2, when the rope projection is released. The movement of the detaining member from the unlatched to the latched position is performed by the rope pro jection itself striking against the forked projection 27 and oscillating the detaining member to such a position that the latching mechanism engages the projection 29.,

The latching and unlatching mechanism in its preferred form may be described as fol lows: H are two dogs respectively pivoted to the frame at 30 and 31. Each of these dogs contains an inclined deflecting-head 32, an inwardly-facing hook 33, an outwardlyfacing hook 34, and a hump between said hooks. Said dogs U are held in position by the levers m m, both of which are fulcrumed upon the same pin 36, upon which the pawls n and n are pivoted. Each of the levers m and m makes at its upper end a pin 37 and slot 38 connection with one of said dogs, and the upper arms of said levers are held together by the spring 39, the tendency of which is to hold the said levers at the inner ends of said slots, and therefore maintain the dogs land Z in the horizontal position shown in Fig. 5, though each of said dogs is free to be moved downward in antagonism to said spring, either by a downward pressure upon the dog itself or an upward pressure on the lower arm of its lever. The lower arm of each of the levers m and m extends under that pawl which is opposite the dog with which the lever is connected, so that whenever one of the dogs is depressed the opposite pawl will be raised into unlatching position, (see dog Z and pawl a of Fig. 2,) while whenever the dog is in horizontal position the pawl opposite to it will be in latching position. (See dog Z and pawl 11 Fig. 2.) each lever m and m/ is fixed a finger 0 and 0, which respectively project into the path of oscillation of the pins 40 and 41, mounted, respectively, upon the detaining members I: and When the load is lifted and the counterweight lowered to its rest, the rope will pull the carriage until the roller is transferred from hook 34 to hook 33 of the dog. The pin 40 moving upward will raise the finger 0, so as to depress the dog Z and permit the roller to escape from the hook 33, so that the rope can continue pulling the carriage along the trackway until the dog Z encounters the roller on the other hanger, p.

1) and p are hangers, each of which is secured on the under side of the trackway by the clips 42 and 43 and each of which supports at its lower extremity a horizontal transverse convex roller 44 and also the downwardly extending diverging weighted arms 45 and 46, which tend to hold the hangers in proper position. As the load-carriage travels along the trackway the rollers 44 are thus held in the paths of the dog-heads 32.

The operation of the detaining latching and unlatching mechanisms maybe described as follows: hen the carriage is conveying the load along the trackway, the parts are in the position shown in Fig. 5, where the two rope projections j and j are both held by the detaining devices, which are in turn held by the pawls n and 11/, both counterweights being supported on the rest. hen one of the dog-heads collides with one of the rollers 44, the dog is depressed, admitting the roller into its hook 33 and over its hump 35 and into its hook 34, being the position shown at the left of Fig. 2. This depression of the dog causes the rear end of its lever to raise the opposite pawl into unlatching position and permit the detaining member to drop into the position shown at the right of Fig. 2, setting free one of the rope projections, as

j, the other rope projection still remaining detained byits detaining member. This condition will continue until the fall-block has descended and ascended, whereupon the rope projection by contact with the arm 27 will raise the detaining member Z: to and beyond its first or latching position until the pin 40 has depressed the dog below engaging position with the roller 44, whereupon the carriage will start along the trackway. Then the detaining member 7': will drop back until the pawl falls behind the projection 29, as shown in Fig. 5. This is the carrying position, the weight of the load being supported upon the detaining members and the counter- Upon the lower or rear end of weights upon the rest, so that the actuator is only called upon to propel the carriage.

Each counterweight should be heavy enough to overbalance the load. y

In the modification shown in Figs. 8 and 9 the rope i extends from the actuator G and sheave 56 at the head to the tail-sheave 50, thence around the sheave 51 of the block from which the counterweight 72 is suspended; thence back to the load-carriage frame, where its end is made fast at 52. The rope extends from the opposite side of the actuator G over the head-sheave 57 and carriagesheave 53 under the fall-block sheave 54 and has its end made fast to the load-carriage frame at 55. It contains the projection or enlargement 1' and the load-carriage contains the detaining member k for cooperating with the dog-Z and hanger p and paw] if, in the manner already described in connection with the form first described, through the arm 0 and projection 61. A hook 59 on the hanger 6.0 acts as a stop for the-stud 58 onthe detaining member If to limit the downward movement thereof.

It will be observed that the apparatus shown in Fig. 1 is double-acting, having two hoisting and lowering stationsPand P, while theapparatus shown in Fig. 8 is single-acting, its hoisting and lowering station being at P In both the double and single acting constructions the carriage traction-rope-which draws the carriage toward a station remains fixed to the carriage, while the other rope in performing the lowering and hoisting has a running engagement with the carriage. In the single-acting construction the same rope may always give this traction and may therefore be permanently fixed to the carriage, as inFig. 8; but in the double-acting construction each rope is called upon to give the .traction toward one station and thelowering and hoisting at the other station. In other words,

in the single-acting construction one run of the looped fall-rope may be permanently fixed to the carriage, while in the double-actmg each run is disconnected at the station at which it iscalled upon to do the lowering and hoisting. Therefore in the double-acting the fixing of each .rope' to the carriage is temporary. I use the term fixed to the carriage to include, broadly, both construe-- tions, whether the fixing be permanent or temporary, andI use the term carriage traction-rope to include, broadly, both constructions, whether the rope act permanently as the traction-rope or only temporarily toward one'of two stations, and I also use the term hoisting-rope broadly to cover both constructions, whether the same rope. always or the two ropes alternately act as the hoistingrope. In both the single and double acting constructions the counter actuator. or weight of the carriage traction-rope is in action when the-carriage is stopped and the loweringv andv opposite sides of said fall-block.

8. In combination, a tra'ckway, a carriage hoisting is being performed by the other rope, and through the operative connection between the primary actuators of the two ropes (whether this connection be made by the use of a singledrum, as in Fig. 8, or two connected drums, as in Fig. 1, or by any other suitable connection) the counter actuator or weight has a reciprocal connection with the load,

whereby it assists the primary actuator in I 51 of the single-acting construction andthe.

corresponding runs in the (for the time being) traction-rope of the double-acting construc" tion furnish a rope reserve permitting the prime actuator mechanlsm to continue running after the traction-rope has pulled the car- 'riage to the'station.

Although the double and single acting con-' structions contain the above and other generic features in common, they nevertheless severally contain other Very important features of invention. For example, when constructed in the preferred form: shown the double-acting apparatus enables a load to be hoisted at one station and conveyed to and lowered at another stationby the use of only two ropes extending from the prime actuator mechanism to the carriage, the rope which acts as the traction-rope toward one. station acting as the hoisting and lowering rope at the other station, and vice versa; Moreover,the hoisting at one station and the conveying to and lowering at the other station may 'all'be done without stopping or reversing the actuation of the two ropes by the prime actuator. In other words, when 'the prime actuators g g" are started to hoist the load at one station they need be neither stoppednor reversed till the load has been conveyed to and lowered at the other station.

Having thus described my lIlVGIliSIOIL'I claim as new and desire to secure by Letters Patent' 'ITS anism' for actuating the rope inboth directions and a counter-actuator operating upon said rope on each side of said fall.
